Question for designers. Acive or passive??


Please have a look at this and tell me if this is active or passive design. I see no active parts in the signal path, company claims this as to be active. ????

It is active in the sense that power is required to charge the dielectric.
OK, but I still don't understand what or how the charge affects the sound???
Dunno.
